실험 절차

Acetic anhydride (0.039 mL, 0.41 mmol) was added to a solution of 4-benzyl-N-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-2-amine (175 mg, 0.41 mmol, example 109) in THF (3 mL) and stirred for one hour. The solvent was evaporated under reduced pressure and the crude product purified on prepHPLC yielding 1-(4-benzyl-2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenylamino)-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)ethanone (64.0 mg, 33.3%).
